98000160100 Rev D FLEXmax Spec Sheet[1]

1 Increases PV Array Output by up to 30% Advanced Continuous Maximum Power Point Tracking Full Power Output in Ambient Temperatures up to 104 F (40 C) Battery Voltages from 12 VDC to 60 VDC Fully OutBack Network Integrated and Programmable Programmable Auxiliary Control Output Built-in 128 days of Data Logging Standard 5 Year WarrantyContinuous Maximum Power Point Tracking Charge ControllersThe FLEXmax family of charge controllers is the latest innovation in Maximum Power Point Tracking (MPPT ) charge controllers from OutBack Power Technologies. The innovative FLEXmax MPPT software algorithm is both continuous and active, increasing your photovoltaic array power yield up to 30% compared to non-MPPT controllers.

2 Thanks to active cooling and intelligent thermal management cooling, both FLEXmax charge controllers can operate at their full maximum current rating, 60 Amps or 80 Amps respectively, in ambient temperatures as high as 104 F (40 C).Included in all of the FLEXmax Charge Controllers are the revolutionary features first developed by OutBack Power, including support for a wide range of nominal battery voltages and the ability to step-down a higher voltage solar array to recharge a lower voltage battery bank. A built-in, backlit 80 character display shows the current status and logged system performance data for the last 128 days at the touch of a button.

3 The integrated OutBack network communications allows FLEXmax series Charge Controllers to be remotely programmed and monitored via a MATE system display and provides unrivaled complete system MPPT Charge Controllers are the only choice when you demand a high performance, efficient and versatile charge controller for your advanced power From: maxTM60 maxTM80 Nominal Battery Voltages 12, 24, 36, 48, or 60 VDC (Single model - selectable via fi eld programming at start-up)Maximum Output Current 80 amps @ 104 F (40 C) with adjustable current limitMaximum Solar Array STC Nameplate 12 VDC systems 1250 Watts / 24 VDC systems 2500 Watts / 48 VDC systems 5000 Watts / 60 VDC Systems 6250 WattsNEC Recommended Solar Array STC Nameplate 12 VDC systems 1000 Watts / 24 VDC systems 2000 Watts / 48 VDC systems 4000 Watts / 60 VDC Systems 5000 WattsPV Open Circuit Voltage (VOC)
